Question

(2/6) elevado a menos 3

Answer 1

Potenciação

Temos:

$\red{\boxed{\orange{\boxed{\rm \Bigg(\dfrac{2}{6}\Bigg)^{-3}}}}}$

Como temos expoente negativo, utilizamos a propriedade:

$\boxed{\boxed{\sf \Bigg(\dfrac{a}{b}\Bigg)^{-n} =\Bigg(\dfrac{b}{a}\Bigg)^{n} }}$

Fazemos:

$\red{\boxed{\orange{\boxed{\begin{array}{rcl}\\&{\tt \Bigg(\dfrac{6}{2}\Bigg)^{3} =\dfrac{1^{3}}{3^{3}}=27}&\\\\\end{array}}}}}$

Temos a Resposta:

$\red{\Large\boxed{\sf 27}}$
